  • Does the fact that nobody has come to visit us from the past or future mean that time travel is impossible?

    Best answer: I think that that is close to what Hawking says. People like Ronald Mallet though are actively studying time travel. I for one would think that if it is posible then they must not be able to interact with us in a physical way...otherwise we would have incountered them already. Maybe it would be more like you... show more

Maybe it would be more like you being a type of ghost like representation in which you can see and hear things of the past as if you were there but you have no way to physcially interact with anything. I am sure people have thought of this already

  • The entropy of the universe is continually increasing, how did it decrease in the first place?

    If you leave an isolated system to its own, its total entropy will never decrease over time. That's the 2nd law of thermodynamics, and that's just the nature of matter. The system tends to get more and more disorderly over time. But how did the entire universe, as an isolated system, start at a low entropy... show more
    If you leave an isolated system to its own, its total entropy will never decrease over time. That's the 2nd law of thermodynamics, and that's just the nature of matter. The system tends to get more and more disorderly over time. But how did the entire universe, as an isolated system, start at a low entropy state? How did any "order" appear in the first place? Isn't that against the 2nd law, and against how matter would behave on its own?

  • Why do we lack a holistic understanding or development of physics?

    Best answer: The standard model only describes what happens----we do not know the WHY yet. There are SEVERAL different Physics theories that attempt to do so, but NONE explain every aspect of the model---some explain some and others explain others.---It is APPARENT that we STILL do not have enough pieces of the puzzle,... show more

There are SEVERAL different Physics theories that attempt to do so, but NONE explain every aspect of the model---some explain some and others explain others.---It is APPARENT that we STILL do not have enough pieces of the puzzle, evidence and experiment wise to come up with a holistic explanation.-------Currently, I favor the HUT (Holographic Universe Theory) physics explanation, as it has more potential to explain the most.--especially some of the stranger aspects that appear to be dependent on MIND and observation.

  • Is an electric scooter the future of transportation?

    Best answer: It may be in the countries where scooters are a primary form of transport. There is a large infrastructure in many countries that support petrol scooters and tuc tucs, this, it's hoped, will eventually go electric - but only if buying an electric scooter is as cheap or cheaper than a petrol one.

    Best answer: It may be in the countries where scooters are a primary form of transport. There is a large infrastructure in many countries that support petrol scooters and tuc tucs, this, it's hoped, will eventually go electric - but only if buying an electric scooter is as cheap or cheaper than a petrol one. In economies where scooters have a lifespan of tens of years it's going to take some time for electric vehicles to take over - but it should happen.

    Imagine if, whilst stuck in traffic, you were not wasting energy. If you see some of the jams in India it should be a no brainer to go electric.

  • Can a cell phone produce enough energy to be used as a defibbrillator?

    Best answer: Possible. I can't find good info on the requirements, but I did find one reference that said 100-200 J Energy is the important factor, voltage can always be generated. Cell phone capacities are about 2 amp-hour, which is the same as 2 amp-hour x 3600s/h = 7000 amp-sec = 7000 J So the battery has the... show more
    Best answer: Possible. I can't find good info on the requirements, but I did find one reference that said 100-200 J

    Energy is the important factor, voltage can always be generated. Cell phone capacities are about 2 amp-hour, which is the same as
    2 amp-hour x 3600s/h = 7000 amp-sec = 7000 J

    So the battery has the capacity for quite a few shocks. But the battery energy is not available to the outside world, to my (limited) understanding, and you would need an external adaptor of some sort.
